  • Spatially-Selective Sampling of Gut Microbiome
    Publication number: 20240000441
    Abstract: An orally-administered gut sampler traverses the gut and obtains a sample of a bacterial population that is present at a selected location within the gut. The sampler has a body that extends from a proximal end to a distal end along a longitudinal axis thereof. The body includes an inlet at the proximal end and a sample chamber distal to the inlet. A sample of bacteria begins to pass into the inlet and into the sample chamber when the sampler arrives at the selected location.

  • D/A Converter With Resistive Interpolation
    Publication number: 20230353165
    Abstract: A digital-to-analog converter that outputs an analog value representing a digital value includes a decoding stage and an interpolation stage. The decoding stage defines upper and lower bounds and the interpolation stage outputs an interpolated value that is between the upper and lower bounds. The upper and lower bounds are based on a most-significant portion of the digital value. The interpolation stage selects the interpolated value based on the least-significant portion of the digital value.

  • Reel-to-Reel Fabrication of Coated Threads
    Publication number: 20230173711
    Abstract: In an apparatus for manufacturing a coated thread, a thread extends between first and second spools and passes through a cartridge having ink reservoirs in which the stretched thread is dipped while the thread and a sensor that provides, to a controller, a value of a parameter indicative of an extent to which the thread has been dipped in the ink reservoir. The controller uses this parameter as a basis for controlling rotation of a motor that rotates one of the spools.
